Specification of Letters Patent.

Application filed June 13' 1907. Serial No. 378.769.

Patented. Feb. 11, 1908.

To all whom it may concern:

Be it known that 1, WILLIAM 0RD, a citizen of the United States, residing at Brooklyn Station, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Valves; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has relation to new and useful improvements in stop valves for high pressure fluids, and has for its main object the production of a simple and economical valve of this character having two valve members, the inner one being capable of ad justment to compensate for wear.

With theseobjects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a side elevationof a valve constructed in accordance with the invention Fig. 2 is a central vertical sectional view of the same, the valve open; Fig. 3 is a horizontal sectional view of the valve on the line 3-3 of Fig. 2; and Fig. 4 is a top plan view.

Referring more particularly tothe drawings, the numeral 1 represents a hollow elbow casing adapted to be screwed to water pipes.

The numeral 2 represents an outer stationary valve member having a circular head, 3, and a hollow cylindrical elongated body, 4, having four or more longitudinal slots or valve openings, 5, spaced equal distances apart, and an inner slanting wall, 6, the purpose of which will be shown.

In the application of my invention the body of the said valve member 2 works vertically in said elbow casing 1, and is removably secured in position by screws 7, working through. corresponding openings in the head 3 of said valve member and screwing in an annular flange, 8, at the upper end of said elbow casing.

The numeral 9 represents 'an inner revoluble valve member comprising a circular head 10 provided with a central vertical opening 11, and a downwardly extending hub, 12, and a hollow, elongated body, 13, flared outwardly to correspond with the slant of the inner wall of the body of said stationary valve member, having a plurality of slots or valve openings, 14, corresponding with the slots or valve openings in the body of said stationary valve member.

The numeral 15 represents a stem which is secured to and works through the central vertical opening 11, in the head 10 of said inner revoluble valve member 9, and is provided at its upper end with a screw-thread, 16, to receive the interiorly threaded head, 17, of a gland or follower, 18, having an elongated body, 19, working in a hollow exteriorly threaded member 20, screwing in a corresponding screw-threaded opening in the center of the circular head 3 of said outer stationary valve member 2, and having a hexa onal head 21.

A dock nut 22 comprising an elongated cylindrical body 23 having an annular, outwardly extending flange 24, provided in its edge with a number of corresponding recesses, 25, is screwed to the upper end of said stem 15 above said gland or follower; and the body of said lock nut works through a corresponding vertical opening 26 near the center of a horizontally disposed yoke 27, adjustably and removably secured to the upper threaded ends of bolts, 28, by nuts, 29, disposed on opposite sides of said yoke. The outwardly extending annular flange of said lock nut works on the upper face of said yoke.

The numeral 30 represents a'horizontal clamping plate, which is removably secured at its outer end to the upper end of one of said bolts 28, and normally clamps the upper end of said lock nut, 22, at its inner bifurcated end. A look screw or bolt 31 works through a corresponding vertical opening near the inner end of said horizontal clamping plate, and screws in said yoke 27.

The numeral 32 represents a horizontally disposed handle, which is removably secured in any desirable manner to the upper end of said stem above said yoke and clamping plate 27 and 30, respectively, and serves as a means in turning said stem. A stop screw 33 is screwed to the under face or side ofsaid turning handle, 32, near its inner end, and its head is adapted to engage the head of a stop screw, 34;, screwed in and near one edge of said yoke, 27, when the valve is closed and is adapted to engage the head of a stop screw, 35 screwed in one of aseries of vertical screwthreaded openings, 36, in said. yoke when the valve is open. The body 4 of said stationary valve member 2, is made somewhat longer than the body 13 of said revoluble valve member 8, to provide a space between the heads 3 and 10, respectively, of said valve members, so that said inner revoluble member may be moved up when the bearing surfaces of said valve members have undergone sufficient wear to cause the valve to leak.

When my improved stop valve is applied first to use, the lower end of the body of the inner revoluble valve member works on an inwardly extending annular flange, 37, of said elbow casing, and the longitudinal slots or valve openings of said valve members exactly register when the valve is open. To adjust said inner valve to compensate for wear, it is only necessary to turn said lock nut to effect an upward movement, and valve stem, 15.

Having fully described my invention, what I claim as new and desire to secure by Let ters-Patent, is:

1. In a stop valve, the combination of an elbow casing, an outer stationary valve member fitting in one end of said casing, an inner revoluble valve member working in said stationary valve member, a stem secured to said inner revoluble valve member, a lock nut screwed to the upper end of said stem, means carried by said outer valve member for adjusting said stem vertically, with means for locking said lock nut in position.

2. In a stop valve, the combination of an elbow casing, a valve member having a hollow cylindrical body with an inner slanting wall adapted to be secured in one end of said casing, an inner revoluble valve member having a hollow outwardly flared body of less length than the body of said outer valve member, a valve stem having a thread at its upper end secured to said inner valve member and working through said outer valve member, a lock nut screwed to the threaded end of said stem, and means for adjusting said stem vertically, with means for locking said lock nut against rotation.

3. In a stop valve, the combination of an outer valve member, a stem having a thread at one end working vertically therethrough, a lock nut screwing on the threaded end of said stem, a clamping plate arranged horizontally above said valve member, a lock screw working through one end of said clamp and adapted to co-act therewith in locking said lock nut against rotation, and means for adjusting said stem vertically.

4. In a stop valve, the combination of an outer valve member, a yoke arranged horizontally above said member, a lock nut working in said yoke, a threaded stem working through said lock nut, a clamping plate arranged horizontally above said yoke, and a lock screw screwing through one end of said plate and adapted to co-act therewith in locking said lock nut against rotation, with means carried by said valve for supporting said yoke.

5. In a stop valve, the combination of a horizontal yoke, a cylindrical lock nut having an annular bearing flange working through said yoke, a clamping plate arranged horizontally above said yoke and adapted to clamp one end of said lock nut and a lock screw working through one end of said clamping plate adapted to co-act therewith in locking said lock nut.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

WILLIAM 0RD.
